Well, the default templates miss the necessary code to actually open 
files in any way. Though they are actually already quite advanced, 
they are really templates that you need to expand upon and are not 
able to just open any file you throw at them. So if your app needs to 
be able to read a document, you need to add code for that. 
Furthermore, you indeed need to enable the app for the file type (or 
enable all files by entering a *). Look at the "build a text-editor in 
ten minutes" tutorials that are available at several places on the web 
for examples how to do this stuff.

Good luck, Patrick
